Data::Dump::Streamer looks great... But I'm trying to keep to core modules.
I'm coming up with another solution I think will work for my scenario. I'll post it shortly.
My program has lots of user account and lots of different config options for each one. Calculations are made based on the options. When sorting through making overall calculations for a long list of users I need to be able to change variable values quickly. Some accounts will use default values, others part of a group of values and others individual. Main user data is obviously stored in a database, but these variables are stored in small flat files for quick access.
